/etc/courier directory is owned by courier.admin with 775 permissions. /etc/courier/hosteddomains is owned by courier.courier with 775 permissions. /etc/courier/esmtpacceptmailfor.dir/* is owned by courier.courier with 775 permissions.

/usr/lib/courier/sbin/makehosteddomains is owned by courier.admin and has been chmod'd u+s.

/usr/lib/courier/sbin/makeacceptmailfor is owned by courier.admin and has been chmod'd u+s.

So, if I then have a system user called 'test' who is a member of the 'admin' group, I should be able to login as that user, run the 'makehosteddomains' program, and have my hosteddomains.dat file updated.

BUT.. it doesn't work. It complains that it cannot make hosteddomains.tmp. If I hack about with the command line options to make the temporary file somewhere else (eg, /tmp), it then makes the file, but complains that it cant replace the original copy that's sitting in /etc/courier.

I *really* need to get this working, so any input would be useful!
